Protoscope is a utility that aids Web developers by revealing the HTTP communication while they interact with their applications. It acts as an HTTP proxy, so that developers can configure their browser to use Protoscope as a proxy and then view the HTTP transactions as they browse.
PHP-Proxy is a PHP script for taking Web pages from one server, so that your main server is protected if the Web server is overloaded from things like DOS attacks. It is also very useful if you have a machine behind a firewall that you want to be your server for Web pages, provided that the machine running the proxy has port 80 open. Finally, there is encryption to defeat filters on specific words if need be.
LiteSpeed Web Server is a high-performance, secure, easy-to-use, and Apache interchangeable Web server. It supports HTTP/1.1, SSL, CGI, FastCGI, LSAPI, PHP, JSP, Servlets, GZIP compression, chroot, IP level throttling, connection accounting, DoS attack prevention, and instant recovery mechanisms. With its Apache compatible rewrite engine, .htaccess, and MS FrontPage support, migration is quick and easy. A Web interface is included for administration and configuration. It can be used as a content accelerator, compression proxy, or a security guard running in front of any Web and application server.
CECID (The CEnsorship CIrcumvention Device) is a PHP script designed to anonymize and filter HTTP requests, especially for users behind restrictive firewalls (e.g. workplaces, schools, etc.). It remotely loads a page that a user specifies, and filters it for words on its 'weighted phrase list', a list of words commonly blocked by network administrators. It alters these words to avoid detection, and displays the page requested. It can also be used for anonymizing HTTP requests, for situations where cloaking and security are required.
Squidwall is a small and very fast squid redirector. It enables the administrator to build an easy-to-use Web interface for controlling user-, host-, or IP-based access to squid. It also supports filtering of Web pages containing obscene content with an advanced phrase weighting system like Dansguardian. It supports pass-through antivirus scanning with clamav, banner filtering, whitelisting and blacklisting via regular expressions or string comparison based on URLs and/or content. The default Web interface can be used by teachers for disabling, enabling, or filtering access to the Internet.
Proxy Detector is a PHP class that can detect HTTP requests via proxy. This class can detect if a visitor uses a proxy server by scanning the headers returned by the user client. When the user uses a proxy server, most of the proxy servers alter the header. The header is returned to PHP in the array $_SERVER.
